m IMPROVEMENT IN HEMMER, FOR SEWING-MAGHINE. a his fidgehizle tticrhh in in time iettas ijdnhn-t mm making and at the same;

M TO ALL TO WHOM IT MAY CONCERN:

Be it known that I, Jenn Monnrsozv, of Birmingham, in the county'of Warwick, England, machinist, a subject of the Queen of Great Britain, have invented or discovered new and useful Improvements in Hem- Folders and Tuckers for Sewing-Maehines;" and I, the said JQHNLIORRISON, do hereby declare the nature of the said invention, and in what manner the same isto be performed, to be particularly described and ascertained in and by the following statement thereof;- that .is to so.

My invention consists of the improvements in or additions to hem-folders, of the kind described in the specification of Letters Patent granted to me in the United States on the 7th day of July, 1863. I

In constructing hem-folders according to my present invention, I form the said folder atthe end of an arm hinged to a base-plate, the said arm being capable of being turned on its hinge in a vertical plane for the purpose of introducing the fabric to be hemmed. The said base-plate is not, fixed directly to the sewing-machine, but is jointed by a rule-joint or other jdint to a connecting-piece fixed to the sewing-maehine. By means of the said joint the base-plate can be turned at pleasure in a horizontal plane out of the way of the needle of the sewing-machine. I

p The arm carrying the folder is graduated into inches and parts of inches, and upon the said arm is a springslide, by regulating the position of which on the arm, the width of the ham, or of the tack, when the instrumient is used as a tucker, as hereinafter explained, may be determined. The said slide also serves to fix down'the arm carrying the folder, the said slidchaving a finger or projection which engages under the edge of a slot in the base-plate parallel to the said arm When it is wished to raise the arm, theslide is pushed back on the arm till the finger or projection comes opposite to a cross-slot, when the arm can he raised, the finger or projection being disengaged from under the edge of the plate.

To the end of the arm, and immediately over the folder, a spring-plate may be placed, the said spring-plate having a slot in it through which the needle works. The said spring-plate serves to guide the edge of the hem, if desirable. I

When the instrument is used as a tucker, the fabric is passed under the folder-and arm carrying it, until ainst the slide-which has been ad usted on thc'arm'to the required width-of the tuck. Having explained the nature of my invention, I will proceed to describe, withreference to the accompanying drawing, the manner in which the same is to be carried into effect. I

Figure 1 represents in plan, Figure 2 in side elevation, and

invention.

Figure 4 represents the base-plate of the folder turned aside upon its joint.

Figures 5 and 6 are parts of the same, as hereinafter explained.

The same letters of. reference indicate the same parts in each figure oi the drawing.

a is the folder, constructed of two helical plates of steel, according to the patent hereinafter referred to, the said folder being formed at the end of the arm 6 hinged at b to the base-plate a. This base-plate cis jointed by the rule-joint d to the connecting-piece e fixed to the sewing-machine. ns d of the rulc-jointd any, other convenientjoint may be used. a Y a a.

By means of the joint d,.the base-plate e and parts carried by it may be turned.in a horizontal plane out of the way of the needle of the sewing-machine, as represented in fig. 4. The foldera and arm 6 are made by preference from one piece of steel, that is, the arm 6 has a forked piece on its end which is fashioned into the folder a. The folder a may, however, be made of a separate piece of steel attached to the said arm 15. The

Figure 3 in and elevation, a hem-foldengwhich may also be used as a tucker,) constructed according 'to my arm, 6, may bc raised in a vertical plane, as indicated in dotted lines in fig. 2, when it is wished to introduce the fabric to be hemmed between the plates of the folder at.

The arm, I), is graduated in the manner represented in figs. 1. and 4, and on the 'said arm is a spring-slide, ff'-',-by regulating the position of which on thearm b the width of the hem or tuck may be determined.

By an examination of the drawing, will beseen that'the spring-slide 'consists of a eross-plate,f, and a spring-clip,f which clip slides upon the arm b/and holds the slide firmly in any position in which it is placed on the said arm. lhe said spring-slideff" also'serves tofixdown the arm 12 carrying the folder a. The fixing down of, the arm 6 is efieeted by means of a. finger or projection, f, on the eross-plate'fpassing through the slot b and engaging under the edge of the base-plate a By moving the slideff until its finger or projection) eomesopposite the cross-slot g in the plate 0, the fingerf is liberated, and may be lifted through the said cross-slot, and-the arm b and parts carried by it raised from the base-plate c, asjndicated in fig. 2. The springslide is represented separately in fig. 5. Instead of jointing the graduated arm to a base-plate, of the kind represented, the said arm maybe jointed-to any otherconvonient part of the sewing-machine.

Immediately over the folder a is ,a. spring-plate, h, for the purpose of guiding the edge of the hem as it emerges from the folder d, the needle of the sewing-machine working through the slot k in the said plate. The

V under side of the free end of the spring-plate it has a. longitudinal shoulder, h, against which the edge of the hem bears, and is thereby guided. An under side and cross-section of the'spring-plate b are represented in fig. 6, by an examination of which fig. 6 the construction of the shoulder for guiding the edge of the hem will be i-eedily.understood. The 'said spring-plate is not fixed rigidly to the arm I), but is jointed thereto at 72-,50 that,

when necessary,.it may be turned out-of the way of .the needle, as. indicated in dotted lines in fig. 1. Thisspri'ng-plate may be dispensed with, as it is not necessary in all cases to use it.

When the instrument is usedas a tucker, the fabric is passed under the'folder a. and arm 6, that is, between the folder a and base-plate 0, until it comes against the'slide ff, which hasbeen adjusted on the arm 6 to the required width of the tuek. k I

, Having now described the nature of my invention, and the manner in which the same is to be performed,

I wish it to he understood that I do not limit myself to the precise details herein described and illustrated, as the same may be varied without departing from the nature of my invention; but

I' claim as my invention of improvements in hem-folders and tuckers for sewing-machines- 1. .The heni-folder a, in combination with the graduated jointed arm I) and horizontally-swinging base-nlate c, substantially as and for the purposes herein shown and set forth.

- 2.. The combination, with the graduated arm b and base-plate c, of the spring-slide f f f, constructed and .used.substantially as herein shown and described.

3. The combination, with the hem-folder a, graduated jointed arm I), and base-plate c, of the spring-plate h h h", jointed to the arm b at hysubstantially as and for the purposes set forth.
